Billy is an outstanding asset! At CharlesCannon he was one of the key persons helping conceive and designing the website for Worthy Children Foundation's exceptional website. His combination of technical expertise and strong communication skills is unparalleled, and I remain deeply grateful for his unwavering support. Billy is our trusted web maintenance and innovation expert, ensuring that our website runs smoothly and efficiently. I cannot recommend Billy highly enough for any web development needs.

Bill has been an excellent mentor. His structured approach and dedication helped me build confidence and stay focused. He's always encouraging, bringing good energy to every lesson, and genuinely cares about his students success. His guidance not only improved my skills but also gave me the mindset and confidence to keep going. Thanks to his support, I landed my new job, and I couldn't be more grateful!

It was a sport data analysis. It was delivered under 5 hours, from fetching the data to provide correct output including intuitive error messages. Incredible!

Suite à une reconversion professionnelle, je suis actuellement étudiante en physique à l'Université de Genève. Grâce à l'aide précieuse de Billy et à sa remarquable pédagogie, j'ai pu valider mes cours d'informatique en Python avec grand succès.

Billy est une personne brillante et déterminée, toujours prêt à aller au bout de ses idées avec intelligence et efficacité. Il m'a aidé à structurer mon travail de manière plus fluide et m'a apporté un regard précieux sur mes projets artistiques. Son énergie et son sens de l'initiative sont inspirants, et travailler avec lui est un vrai plaisir.
